GEORGE S. CONGER, OF NEW YORK, N. Y., ASSIGNOR TO DOW, JONES & COMPANY, A JOINT-STOCK ASSOCIATION OF NEW YORK.

INKING MECHANISM.

Application filed February 19, 1919.

To all whom it may concern:

Be it known that I, GEORGE S. CONGER, a citizen of the United States, residing at New York city, N. Y., have invented certain new and useful Improvements in Inking Mechanisms, of which the following is a clear, full, and exact description.

My invention relates to an inking mechanism particularly adapted for use on printing telegraph machines, in which the matter is written on a broad page as distinguished. from a narrow tape of paper. My object is to provide an improved and simplified inking construction.

In the preferred form of my invention shown in the drawings, Figure l is a front elevation of one type of page printing machines with my improvement thereon;

Fig. 2 is a top plan view in section on the line Y of Fig. 1;

Fig. 3 is a side elevation of the typewheel, inking rollers and carriage; I

Fig. 1 is a detail of the ink reservoir;

Fig. 5 is an enlarged section thereof on the line XX of Fig. 2, showing also the wiper;

Fig. 6 is a detail view of the wiper sprlng; and

Fig. 7 is an enlarged view of the ink reservoir and wiper showing also typical positions of the inking roller.

The invention is in the drawings shown as applied to my page-printing telegraph receiver illustrated in United States Letters Patent #1,178,215 dated April l, 1916. In the drawings there is provided a type-wheel 1 rotated by a type-wheel shaft 2 on which it is longitudinally slidable, being connected thereto by a spline or similar connection. This shaft is put under constant stress by a coil spring 3 operated by winding mechanism a and released by the magnets 5 and escapement 6.

The type-wheel is moved along to the right by a carriage 7 which slides along a squared shaft 8 and is moved step-by:step by a double rack and pawl mechan sm indicated by 9, 10, the movable rack being actuated by the magnet 11 and lever 12, for letter-spacing across the page of paper, not shown. Resting loosely against the typewheel is an inking roller 13, and an additional inking roller 1% may be provided if desired. The circuits and connections (not Specification of Letters Patent.

Serial No. 277,958.

shown) may be as illustrated and described in my former patent above mentioned. The type-wheel is rotated to present the proper letter and print it, and the carriage and type-wheel move to the neXt letter-space as carnage-release position indicated in Fig. 1,

in which the pin 19 mounted on a disk 20 fixed to shaft 2 is in position to be struck by the projection 21. This throws the pawl 10 out of engagement with the racks and allows the carriage to move to the left, as described in said patent. This general type of carriage-releasing mechanism is common in the prior art and its operation will be evident to a mechanic. When this occurs, it is obvious that the type-wheel is held from rotation by the escapement. The operation is evident from my prior patent and it is not thought necessary to describe it more fully herein.

It is desirable to apply ink to the inking roller at times, in order to keep it supplied with ink. Various mechanisms have been devised for this purpose. In the Burry Patent No. 680,693, an ink reservoir is provided witha capillary brush standing in the path of travel of the inking roller so that each time the roller passes across it, ink is applied to the roller. This construction, however, is open to many objections which my construction is designed to avoid. In Burry, the ink is applied twice in writing each line, often resulting in too much ink being applied; also on cold days or when the machine has not been in use for some time, the ink becomes gunnned in the brush and is not applied properly or at all. These and other objections I have overcome.

In the preferred embodiment of my invention, I provide an ink reservoir 22 and an ink-supplying device, which may be in the form of a wiper 23 normally dipping into the ink in the reservoir, projecting therein through a slot at the top, as illustrated in Figs. 4 and 5. This wiper is pivoted at 2d and is raised at suitable times. into contact Patented Feb. 17, 1920.

with the type-wheel, as indicated in dottedlines in Fig. 7. This wiper may be actuated in various ways, but in this embodiment of my invention I have provided a lifting device in the form of a cam-shaped spring 25 which may be actuated at the will of the operator. This may be done in various ways, but in the present embodiment T have pro- -vided a spring finger 26 on the carriage.

Normally, the parts stand as shown in full lines in Figs. 1 and 7. The spring lifter 2G is shown positioned substantially at the extreme limit of travel of the carriage.

As the carriage moves to the right, the finger 26 engages the lifter as shown in dotted lines at 27, the finger being slightly bent upward by the pressure. At the next movement given to the carriage, the end of the finger reaches the cut-away portion 28 of the lifter and snaps down below it, as indicated in dotted lines at 27 in Fig. 7. If the carriage is then released and allowed to move to the left, the finger passes underneath the spring lifter and raises it to the position shown in dotted lines in Fig. 7, raising the ink-supplying device or wiper into engagement with the inking roller as the latter moves to the left.

" It will be observed that in this form of the invention, the ink is applied at one point in the travel of the carriage and during its travel in one direction only, and only when the carriage-release mechanism is in the carriage-release position. The type-wheel is at this time held from rotation.

I have positioned the ink-supplying mechanism so that the ink is supplied to the roller only after the type-wheel has reached substantially the end of its travel allowed by the mechanism. In the ordinary use of such machines, the operator does not write to the extreme limit of travel possible for the type-wheel, but stops his writing several letter-spaces short of it. There are therefore several, usually at least three or four, normally unused letter-spaces at the right, and I have utilized these to put the inking mechanism under control of the operator so that the ink will be applied only when he desires it and by giving one of the parts controlled by the operator, such as the carriage an extraor dinary movement, preferably to the limit of its travel possible. In Fig. 7 I have illus trated the roller 14 as in the second space from the limit of its travel. The first space from the limit of its travel is indicated by the lines 30 at which the finger 26 is in the position indicated by 27. The line 31 indicates the position of the type-wheel at the extreme limit of its travel when the finger snaps down into the position indicated in dotted lines at 29 at the time when the carriage is released. Of course this exact mode of operation is not essential to my invention. But as illustrated and preferred, the operator may write in the usual way and with the usual length of line without applying ink to the roller. If he desires to ink, all he needs to do is to move his type-wheel to the nor mally unused spaces at the right, such as the extreme limit of travel illustrated, and then release the carriage. This will apply the ink auton'iatically. The ink is therefore not applied every time a line is written but is under control of the operator so that he can ink as often or as seldom as he desires, thus obviating many of the objections to the inking devices of the prior art.

I am aware that my invention is not lim ited to the exact form or arrangement shown, but is susceptible of many 1nodifications and I therefore do not limit myself to the construction herein illustrated and described.
